Package elki.algorithm.statistics

Class AddSingleScale

java.lang.Object

elki.algorithm.statistics.AddSingleScale

All Implemented Interfaces:

Algorithm

@Description("Setup a scaling so that all dimensions are scaled equally in visualization.")
public class AddSingleScale
extends java.lang.Object
implements Algorithm

Pseudo "algorithm" that computes the global min/max for a relation across all attributes. FIXME: this should become part of relation metadata.

Since:

0.5.0
